Subject: drm: logicvc: Fix uninitialized variable in probe
Git-commit: 5e8034364c22050b8564060e79947d094a65d45e
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The "regmap" is supposed to be initialized to NULL but it's used
without being initialized.
Fixes: efeeaefe9be5 ("drm: Add support for the LogiCVC display controller")
